Title: New or improved means for lubrication
IPC: B60R17/00
Filed: 1945-03-21
Abstract: 589,405. Lubricating. GIRLING, Ltd., and PITT, H. W. March 21, 1945, No. 7196. [Class 12 (iii)] [Also in Group XXVIII] For supplying lubricant at regulatable periods to parts not requiring a continuous lubricant flow a pumping plunger 12 is operated by a piston 13 moving in a cylinder 10 to one end of which cylinder a pressure fluid is continuously admitted to force back the piston against a spring pressure 15 until at the end of the stroke a communication is opened between the two ends of the cylinder through ports in the piston so that the piston is then returned by the spring pressure, the communication remaining open until the return stroke is completed; an escape port 30 at an intermediate point in the stroke and regulated by a needle valve retards the latter part of the movement so to adjust the timing between deliveries. As shown, lubricant is drawn through an intake pipe 27 and periodically discharged to points of use through a pipe 29 by the pumping plunger 12 which is operated by the piston 13 moving under the action of a pressure fluid, such as from the force-feed oil system of an internal combustion engine or from the suds pump of a machine tool, continuously admitted to one end of the cylinder by a pipe 14. The piston 13 is thus forced backwardly against the pressure of the spring 15 until an abutment 23 carried on a stem 24 causes slide valves 17 extending through the piston body to be moved to open communication between the two sides of the piston whereupon the piston returns under the action of the spring 15 to effect a discharge stroke of the pumping plunger 12, the pressure fluid meanwhile passing through the piston 13 by the slide valves and draining away through an opening 25 at the far end of the cylinder 10. At the end of this return stroke of the piston the slide valves 17 are moved to the closed position by engaging an abutment face 22. The valves 17 are latched in the open or closed position by spring clips engaging in grooves 19 at the ends of the slide valves. The device may be bolted in the crankcase of an engine to draw clean oil from the re-filling compartment, Fig. 3 (not shown), or may be mounted in a glass reservoir which thus shows the lubricant level.

[Classes 35 and 38 (iv).] Exciting ; dynamos, regulating; motors controlling; regulation, automatic; charging batteries. -A dynamo-electric machine has two field windings one of which is supplied from the machine through slip rings and a rectifier, the impedance of that part of this exciting circuit in which alternating current flows being largely capacitative, so that with a generator the voltage is constant over a wide range of speeds and with a motor the speed is constant over a wide range of voltage. The field 6 of a generator 3 is supplied from slip rings on the machine through a rectifier 7, a capacity 11 being inductively connected between the slip rings and the rectifier. An opposing field 5 is excited from a battery 1, which is being charged by the generator, or from any other constant supply. If the generator speed varies the frequency of the voltage at the slip rings varies to cause a change in the impedance of the capacity 11 and therefore a change in the value of the exciting current of the field 6, with the result that the product of excitation and speed of the generator, and therefore its voltage, is substantially constant. A centrifugally operated switch 13 may be provided to open the field circuit 5 when the generator speed falls below a desired critical value. In the case of a shunt wound motor, Fig. 2, the shunt field 23 assists a field 24 which is excited from slip rings on the armature 22 through a capacity 28 and a rectifier 27.

Abstract: 768,066. Launching aircraft and stopping way. SOC. DES FORGES ET ATELIERS DU CREUSOT, and FIEUX, J. March 15, 1955 [March 29, 1954 ; Feb. 28, 1955], No. 7538/55. Class 4. [Also in Group XXIX] Apparatus for braking aircraft on landing or for launching aircraft, of the type having a cable disposed a small distance above the ground, comprises a hydro-pneumatic device operable as a prime mover or dashpot, constituted by a cylinder 1, Fig. 1, containing a piston 2 subject to pressure from liquid supplied from a reservoir 28 containing gas under pressure, the piston being secured to the movable block 12 of a primary tackle having a fixed block 11 and two cables 9, 9a connected to the movable blocks 14, 14a of two secondary tackles having for cables the two ends of a single cable 20, (Figs. 3 and 6,) guided by pulleys 22, 22a, 23, 24, 25 to assume the shape of a parallelogram. In Figs. 1 and 3, the cables 9, 9a are fixed to lugs 10 on the movable block, being taken round pulleys 11, 12, 11 again, 12 again, and then guided by pulleys 13 to the movable blocks 14, 14a. The ends of cable 20 are tied to blocks 14, 14a and are led round pulleys 18, 19 and 18a, 19a, then pulleys 21, 21a and 22, 22a, and round pulleys 23-25 in square formation. When a landing aircraft engages one side of this square, the pull on cable 20 contracts the secondary tackles 15, 15a, and thus the primary tackle, pushing piston 2 into cylinder 1, and forcing liquid past ball valve 29 into the reservoir against the gas pressure. The device is then ready for launching an aircraft as shown in Fig. 6. In this case, a valve 35 is opened to raise a hydraulic jack 30, opening the ball valve 29 to push out piston 2. This expands the primary and secondary tackles, to take in the slack of cable 20 at a rapid rate. For two successive brakings, the cable slack caused by the first braking is taken up slowly by opening a valve 32 of small aperture. For two successive launchings, a pump 33 is used to transfer liquid from the cylinder 1 to the reservoir, to slacken the cables, to permit the disposition of Fig. 6 to be regained. An alternative construction, Figs. 7 and 8 (not shown) ensures that if, e.g., the cable 20 becomes unhooked during a launch, the rate of taking in cable 20 drops to a safe value [see Group XXIX].

Title: Improvements í¡í¡ to the reduction of iron ores
Inventor: CLEMENT CLAUDE
IPC: C21B13/00
Filed: 1962-02-27
Abstract: In a continuous process for the production of carburized iron, the ore is first treated, at a temperature below that at which sintering occurs and for such time that reduction is 70-98% complete, with a reducing gas containing a major proportion of carbon monoxide and hydrogen, the reducing gas being drawn at least partially from the final stage of the process.  The partially reduced ore is then charged below the surface of a bath of carburized iron, oxygen-containing gas also being charged below the surface, the amount of oxygen being such that a minimum quantity of carbon dioxide is liberated.  The bath may be recarburized by blowing in cracked methane or natural gas, or the initial reduction stage may be carried out under such conditions that solid carbon is deposited on the partially reduced ore.  The partially oxidized gases leaving the first stage reduction may be burnt for use in heat-exchangers or may be freed of carbon dioxide and steam and recirculated.
